Remove 'standalone="yes"' from generated XML

Solution 1:

in JAXB that is part of JDK1.6

marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true);

Solution 2:

This property:

marshaller.setProperty("com.sun.xml.bind.xmlDeclaration", false);

...can be used to have no:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

However, I wouldn't consider this best practice.

Solution 3:

You can either use

marshaller.setProperty(Marshaller.JAXB_FRAGMENT, true);

or

marshaller.setProperty("com.sun.xml.bind.xmlDeclaration", false)

to disable the default XML declaration, and then add your custom XML declaration,

<?xml version="1.0" encoding="UTF-8"?>

by

marshaller.setProperty("com.sun.xml.bind.xmlHeaders",
      "<?xml version=\"1.0\" encoding=\"UTF-8\"?>");

to the generated xml, thus avoiding the standalone="yes" property.

Solution 4:

just if someone else is still struggeling with this problem, you may consider using

marshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);

to remove all of the XML declaration and just write your own String at the beginning of your output stream / method
